Specification of Letters Patent.

Patented Feb. 12, 1907.

Application filer. January 11,1906; Serial No. 295,533.

United States, have invented a new and us3- ful Improvement in Envelop-Machines, of which the following is aiull, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

My invention relates to an improvement in or rather an auxiliary attachment to machines ter-making envelops by which such.

machines may make that type of envelop having an opening therein which is covered by sometransparency or paper gummed or otherwise made to adhere to the envelop around the opening in the same.

It is the object of my invention to provide the envelop-machine with. such means or to so adapt thesame that without changing the usual mode and customary sequence of order l of its operation it of envelop.

My invention can best be seen and understood by reference to the drawings; in which I Figure 1 represents in vertical section a may make the above type portion of a. machine containing my inven-.

tion. Fig. 2 shows a section on the line 2 2 of Fig. 1. chine in plan, to which reference will hereinalter be made. A line 4 4 ol F ig. 3. Fig. 5 illustrates in plana type of envelop which I desire to make, the same being shown unfolded. Fig. 6 shows in plan a slight nmdilication in a portion of my improvement, to which reference will hereinafter be made. Fig. 7 shows in detail a part thereof. Fig. 8 shows a section on the line 8 8 of Fig. (i. Fig. 9 shows in side elevation at modification in another portion of the device. Fig. 10 shows the same partin reverse side elevation.

While I desire it-to be understood that my invention, which will now be explained, can be used with other types oi envelop-making machines, it is especially adapted to be used with a type of machine substantially like that shown and described in my Letters'Patent of the United States, No. 672,919, dated April 30, 1.901. I have accordingly embed ied in the present case variouselssential ele"- Fig. 3 shows a portion of the ma- Fig. 4. shows a section on the i so far as they are pertinent to a E derstanding of the present case.

Referring to the drawings, A represents a portion of the frame 'of an envelop-n1aking machine. Supported by this is the picker mechanism, which consists of a rigid support a, in which slides a verticalspindlea, made to reciprocate in amanner welt known to proper unerence need be made to its operating mechanism. At 'the lower, end of the spindle a spindle or connected therewith, so' as to be operated by the same. I have shown two flaps of the envelop-blank and raise the same to a positionto be further manipulated, as customary in the operation of these machines.

at the same time is an auxiliary picker a 1 made oblong in shape, (see Fig. 2,) sov as to enable it to gum that portion of the envelopblank around the hole before described.

The envelop-blanks B are stacked upon a supporting-table a 'placed below the pickers, and the pickers reach them in the operation of their reciprocation through slots cut in an interposed table a, a supplementary slot 0] being .cut in the table to admit of the passage of the auxiliary picker at r 1 Having thus far referred, in connection with the usual operating parts of the envelopmaking machine, especially'to the means of gunnning that portion of the envelop around the hole or opening cut' therein, reference will now be made to the mechanism by w hich the transparency or transparent aper is applied to the envelop for covering t 1e hole or opening in-it. The portion of the machine hich l I have utilized for the purpose above speci- 4 fied is the plunger mechanism used in coni nection with the creasing-table to force the 1 blank down through it into the folding box. It will be unnecessary to explain how the blank reaches these parts from the pickers, the operation being so well known to those skilled in the art. Briefly referring to these 1 parts, which are'arranged upon the frame A, i C represents the plunger upon the end of the plunger-rod. c. D represents the creasing- Q table through the opening (I, in which the [plunger when operated is adapted to pass,

those skilled in the. art. Hence no further refare the pickcrs,which are attached to the" pickers a 11 which are adapted to gum the Supplementing :these pickers and operating or opening cut in it, as

ments of the machine shown in'said patent and E re presents the folding-box, against the one casting, like that shown in. the dravi ings.

from the side bar 0 is a portion 0 on which this hub and set-screw that furnish the means h made larger than the opening in the envelopsufficientsize to entirely cover said opening.

'may contain a large number of transparenii ottom or bed :3 of which the envelop-blank is adapted to be forced by the plunger and i116 flaps thereof afterward folded by the folders E in the ordinary operation of the msehine. r

The plunger (3 may be oi the usual constructionexcept that it carriesa box or cas; ing *3. This box or casing forms practically a part oi the plunger. In it are adapted to be contained a stack of transparencies B, which in the operation of the plunger are destined. to be applied to cover the hole or opening in theenwlop-blank, as will hereinafter be explained. The form of plunger to which I shall first refer is of skeleton form and in ee Figs. 1 and 3.) It consists'of heavy reetangularlynrranged side bars c, 0 c and 0, having flat bottoms forming theface of the plunger. These bars form the main bearing portion of'the plunger. Projecting inwardly is mounted. a hub c, ldcated at about the -iiddleof the plunger. Through the side ofv this huhthere extends a set-screw 0 It is by which the plunger is detachably secured to the end oi the plunger-rod, for the hub is adapted to receive the end of the plunger-rod and become attached thereto a hen the 'setscrew is turned up.

Referring now to the box or casing C, this located upon one side of the plunger out of the way of the plunger;rod and set in slightly, from the outer edges of the bars forming the main portion of the plunger, as before described, so as not to interfere w ith the creasiug-table as the plunger is operated. More over, the relative disposition of the boxor casing is such as iv ill bring it in that ortion of the plunger directly above the ole or opening in the envelop-blank when located over the creasing-table in position to-be operated upon by the plunger.' The box is blank or so as to contain transparencies of The depth of the box or casingis such that it cies. it is open at the bottom and extends down so far that the lower edges of the sides thereof vi ill be substantially flush with the face of the plunger, thereby assisting in its operation and also enabling the bottom. one of the blank transparencies contained in the casing to assume a position likewise substantially flush ith the bottom or face of the plunger.

The blank transparencies are held withintlie box or casing by means of small clips or dividersc which extend inwardly from or under the bottom edges of the casing. These clips aite'arranged upon the ends of rods 0, which are secured or riveted to. the sides of of. -tional or bearing contact of its flaps and. also 'positively by means of the clips 15, forming ger.

the casing near the topedges thereof. This l easgzov w tension of the reds the clips 0 upon the ends thereof may be adjusted to that point.

or position. n here they Mill be just sulhcient to hold the transparencies in the casing permitting, how ever, of the bottom one 'tlu'eoi' being oraun off u ithcutdisturbing the rest,

Certain of the clip-bearing rods pass through slots 0 formed in the sides 0 c of the plunger. As above explained, the casing itself sets in slightly from the outer edges of these sides, and the clip-bearing rods secured to the sides of the casing are also set in by means of the said slots in order that v hen 'the plunger is operated these rods may not contact uith the edge of the creasing table.

Mention might also be made of a means for imparting a slight yielding pressure to the stack of transparencies in the box or. casing to insure the positive feed thereof as the bottom one of the transparencies is successively drawn away, as will hereinafter be explained. This means consists of a presser-bar c, from which there extends upwardly a vertical rod 0". On this red is a spring a, the bottom end of which spring rests upon the presserbar and against the upper end of whie h bearsa;c0llar 0 which is loosely arranged upon the rod c. 'Ihis collar-forms the end of an angular rod 0", socketed in the side of the casing to be vertically movable therein. By this means a constant yielding pressure is imparted to the transparencies in the casing, which also is self-adjusting, as the number of transparencies therein may vary. The means also is such that it may be easily removable when necessary to renew the stack of transparencies in the casing.

The operation of the parts is as follows: Understanding that that portion of the envelcp-blank around the hole or opening there in has been gnmmed by means-of the aux iliary picker a", as before explained, and that theenvelcp-blank has passed tothe creasing-table in the ordinary operation of the machine, the plunger then descending forces the blank through the creasing t'able into the folding-box against the bottom or bed there In this box the blank isheld by the fric the ends of the common goosenecks E adjustably secured to the frame of the machine, and outwardly ,under which clips the flaps of the envelop-blank are adapted to spring after being seatedin the foldingbox by the plunger the casirig thereof containing, .the trans Now during the operation of the plunpicker and box or casihg are preferably made t-ransparencies will be applied to cover the indifferent styles of envelops may vary, and

parencies will have bearing over the hole or opening in the envelop-blank, for, as before explained, it is located to have sucli bearin The effect is that the bottom one of the blan hole or opening in the envelop-blank and will adhere to the gummed surface around the same, so that upon thereturn of the plunger the bottom one of the transparencies thus retained will be pulled out from itsretaining-clips or dividers and divided thereby away from the other transparencies in the box on the plunger and will be left permanently-adhering to the envelop-blank, which is then folded in the usual manner. It isaccordinglyoto be observed that the transparency is applied to cover the hole or opening in the envelop-blank in the usual and con-.

tinuous operation of the machine, old elements of the machine being employed to make this application without interfering'in the least with their usual and normal sequence of operatiom The changed type of envelop can accordin ly be made as fast asthose of the common Form or type.

In Figs. 6 to 10, inclusive, .[-have shown ight modifications of my invention in that t 1e auxiliary picker a and the box or casing carried by the plunger are so arranged and adapted that their positions maybe adjustahly changed. This is a desirable factor, in-

asmuch as the location of the hole or opening it is to me'o't this variation in the position of the hole or opening ion-the envelop that the adjustable parts.

Beforring first to the box or casing on theplunger, I have shown in Fig. 6 a plunger-F made of rectangularly-arranged side bars f f fflj substantially like the plunger before described. Fastening into opposite ones (f f of these bars of the plunger is'a yoke f bear-- ing ahub f intp which the plunger-rod is adapted to extend and be secured by a set screw f. This arrangement. leavesample room for the adjustment within the plunger of the box or casing C for containing the transparenpies. I provide for, the adjustment of the box or casing by attaching to opposite sides thereof by means of boltsf? the respective angle-pieces f j", which are secured to they adjacent side barsf f 3 of the plunger by means of bolts or screws f Then y means of a series of slots cut in these angleepieces through which these screws or bolts extend not only may the lateral or longitudinal adjustment of the box be pro vided, but its vertical. adjustment also. 7 Of course this arrangement for securing t lgfid justment of the box is simply tentativ'and" may be changed without departing'from the spirit of this phase ofmy invention.

Referring now,'in Figs. 9 and 10, to the mode of adjusting the auxiliary picker of,

it is to be noted that the picker is provided with'a bent arm a which extends through a wide slot a", formed in an attachment a, secured to a portion of the frame supporting the picker mechanism. The arm of the picker is adapted to be laterally and longitudinally adjustable in this slot and is held therein at various points of adjusted position by means of adjustable screws a, which extend through the sides of the attachment and engage with said arm, the' screw then being held by means of locking-nuts a.
